Application February 16, 1951, Serial No. 211,378

2 Claims. (Cl. 312-350) This invention relates to drawer guides and has special reference to means for adjustably mounting a drawer guide on the frame members of a drawer opening so that the position of a drawer within the said opening may be adjusted and controlled.

In my application for patent, Serial Number 153,312, filed April 1, 1950, now Patent No. 2,559,322, issued July 3, 1951, I have shown and described a drawer guide, and the instant application is directed to means for adjusting and securing a drawer guide to frame members of a drawer opening.

It is one of my principal objects to provide simple and efiicient means for adjusting and securing a drawer guide in place in such a manner that it will not be jarred or otherwise moved from operating position during normal operation.

Another object is to provide for selective repositioning of a drawer within a drawer opening in a most convenient manner wherein the frame of the furniture does not have to be tampered with, as is the case with present furniture having drawers.

Another more specific object is to provide a cam device1 which controls the lateral adjustment of the drawer gui e.

These and other objects and advantages will become moae apparent as the description of my invention procee s.

In the accompanying drawing forming a part of this application:

Fig. 1 is a vertical sectional view showing my invention installed on a drawer mounted in a piece of furniture.

Fig. 2 is a perspective view of the upper telescopic member of my drawer guide.

Fig. 3 is a similar view of the lower telescopic member of my drawer guide showing one form of my cam adjusting means.

Fig. 4 is a broken top plan view of one end of the device shown in Fig. 3.

Fig. 5 is a similar view to Fig. 4 showing a modified form of my invention.

Fig. 6 is a sectional view on the line 6-6, Fig. 5.

In the drawing, the reference numeral 1 indicates the rear wall of a piece of furniture, 2 the rear transverse frame member which adjustably carries one end of my drawer guide device. The numeral 3 indicates the front transverse member of the furniture frame which adjustably carries the front end of my drawer guide. The drawer front is indicated by the numeral 4, the drawer sides by the numeral 5, the drawer bottom by the numeral 6, and the drawer back by the numeral 7.

My drawer guide comprises an upper member 8 which is secured to a drawer by any suitable means, such as screws or the like, and has an upstanding lug 9 struck from the rear end of the member to provide means to secure the member to the back of the drawer. This upper giemlboer is telescopically carried on the lower guide mem- The guide member 10 is supported on the frame member 3 at its forward end, preferably centrally of said member 3, and at the rear end on the frame member 2, centrally of the latter, of course, to provide for an alined movement of the drawer within the drawer opening.

As means to adjust the position of the drawer and drawer guide within the drawer opening, and to secure same in adjusted position, I have provided openings 11 in each end of the member 10, the openings having substantially parallel longitudinal edges, as shown.

A gemike d 1. i Pr ded w a ula fiq lqed portion 14Kwhich is of'a sizle to fit betw eefi the toothed edges with t e teeth" 1 sasas 'ii the th 12.55 shown. The toothed portion14 ispr'ferably oftlie' same thickness as the body of the member 10, and a flange 15 is provided on the disc 13 and extends outwardly over and beyond the toothed portion 14 so as to overlap the adjacent portions of the member 10 along the opening 11.

The cam 13, while being substantially circular in shape, is secured in place in the opening 11 by means of a bolt 16 which is placed off of the axial center of the cam, as shown, and extends through the transverse frame members 2 and 3 at each end of the member 10, as seen in Fig. 1. A sleeve nut 17 is provided on the lower end of the bolt 16 and has projections 18 thereon which are engaged in the frame members 2 and 3 to hold the nut in place, making it possible to adjust the bolt 16 with only one tool, preferably a screw driver. A lock washer 19 is mounted on the head end of the bolt 16 to insure lasting tightness of the fastening of the cam.

It is deemed apparent that the lateral position of the slide member 10 on the frame members 2 and 3 may be adjusted by loosening the bolt 16, raising the cam 13 to disengage the teeth 12 and 14, sliding the member 10 to its desired position, then dropping the cam back on to the member 10, then rotating same until the teeth 12 and 14 again interlock. The screw 16 can then be retightened to secure the parts firmly in place.

In Figs. 5 and 6, I have shown a slightly modified form of my invention wherein the longitudinal edges of the opening 11 are smooth or non-toothed, as shown at 20, and the small diameter portion 21 of the disc-like cam 22 is also smooth edged and has a flange 23 similar to the flange 15, as shown. The fastening means 16, 17, 18, and 19 are preferably the same as those previously described, and the operation of the device is the same except that the cam 22 does not have to be lifted out of the opening 11 to change the position of the member 10 as previously described. With the bolt 16 loose, the member 10 may be moved laterally as desired; however, with the bolt 16 tightened securely, the cam cannot be moved out of place and holds the member 10 firmly in position.

Having thus described my invention, what I claim is:

1. Means to hold a drawer in adjusted position in a drawer opening having frame members comprising: a drawer slide, a cam carried adjacent each end of said slide, said slide having an opening adjacent each end thereof to receive said cams, said openings being elongated and having a pair of spaced substantially parallel longitudinal edges whereby said cams may be moved longitudinally of said openings, said cams having a circular portion of a diameter to fit snugly between said edges to prevent lateral movement of said slides relative to said circular portion, said cams having a portion thereof fitting over a portion of said slide to hold the parts in assembled relationship, means for mounting the circular portion of said cams so as to be eccentrically rotatable to change the position of said slides relative to the mounting means, said mounting means including means to secure said cams and slide to said frame members once they have been placed in their desired adjusted position.

2. Means to hold a drawer in adjusted position in a drawer opening having frame members comprising: a drawer slide, a cam carried adjacent each end of said slide, said slide having an opening adjacent each end thereof to receive said cams, said openings being elongated and having a pair of spaced opposed substantially parallel side edges whereby said cams may be moved longitudinally of said openings, said cams including a circular portion of a diameter fitting between said side edges and substantially engaging same to prevent movement of said slides laterally of said opening, means mounting the circular portion of said cams within said openings and to the adjacent frame members so that said circular portion is eccentrically mounted relative to the center of said cam, said cams being rotatable on their mounting within said openings and being capable of changing the lateral position of said slide relative to the pivotal mounting of said cams by virtue of their being rotated and without disrupting the longitudinal position of said slide by virtue of the elongated openings whereby each end of said slide is independently adjustable to govern the position of a drawer within a drawer 5 768,591 opening, and said mounting means including means to 797,031

secure said cams and slides in adjusted position; 1,892,058 Judelshon Dec. 27, 2,559,322 Skamser July 3, 2,580,153 Birkec Dec. 25, 1951 Number Name Date Elfborg Aug. 30, 1904 Vivian Aug. 15, 1905
